<Present demand (PV)>
It shows demand value from the time when demand span starts to present time.

<Estimated demand (EV)>
It shows the estimated demand value at the end of demand span according to the using power from the
time when demand span starts to present time.

<Power demand threshold (SV)> It shows the threshold for demand alarm output.
<Ratio of estimated demand (SET.R)> Ratio of estimated demand to power demand alarm threshold.
<Alarm output>
When present demand or estimated demand is satisfied the setting conditions, it output alarm and it
indicates alarm.
